If a food packet contains more oxygen and is stored at a higher temperature, which problem becomes more likely?
Answer and explanation
Correct answer: Rancidity
Rancidity is caused by the oxidation of fats and oils, which produces an unpleasant smell and taste in food. More oxygen provides greater opportunity for oxidation, and a higher temperature increases the rate of this reaction. Galvanisation is the coating of iron with zinc to prevent rusting, so it is not a food-spoilage problem.
